    x86: Unify node_to_cpumask_map handling between 32 and 64bit · de2d9445
    Tejun Heo 提交于
    x86_32 has been managing node_to_cpumask_map explicitly from
    map_cpu_to_node() and friends in a rather ugly way.  With
    previous changes, it's now possible to share the code with
    64bit.
    
    * When CONFIG_NUMA_EMU is disabled, numa_add/remove_cpu() are
      implemented in numa.c and shared by 32 and 64bit.  CONFIG_NUMA_EMU
      versions still live in numa_64.c.
    
      NUMA_EMU's dependency on 64bit is planned to be removed and the
      above should go away together.
    
    * identify_cpu() now calls numa_add_cpu() for 32bit too.  This
      makes the explicit mask management from map_cpu_to_node() unnecessary.
    
    * The whole x86_32 specific map_cpu_to_node() chunk is no longer
      necessary.  Dropped.
